sun.awt.AWTSecurityManager
All known Subclasses: com.sun.xlet.XletSecurity, sun.applet.AppletSecurity,
| AWTSecurityManager | | public class AWTSecurityManager extends SecurityManager (Code) | | The AWTSecurityManager class provides the ability to secondarily
index AppContext objects through SecurityManager extensions.
As noted in AppContext.java, AppContexts are primarily indexed by
ThreadGroup. In the case where the ThreadGroup doesn't provide
enough information to determine AppContext (e.g. system threads),
if a SecurityManager is installed which derives from
AWTSecurityManager, the AWTSecurityManager's getAppContext()
method is called to determine the AppContext.
A typical example of the use of this class is where an applet
is called by a system thread, yet the system AppContext is
inappropriate, because applet code is currently executing.
In this case, the getAppContext() method can walk the call stack
to determine the applet code being executed and return the applet's
AppContext object.
